Urban black and white adolescents' physical fitness status and perceptions of exercise

The modified Harvard Step Test and a 70-item questionnaire based on the Health Belief Model (HBM) were given to 257 high school students, 154 blacks, and 93 whites. Mean age of students was 16.0 years (SD = 1.1) for whites and 15.8 years (SD = 1.1) for blacks. Though more blacks than whites were in poor physical condition (51% females and 27% males vs. 35% females and 16% males, respectively), the difference was not statistically significant. A high level of concurrence existed between individuals in good physical condition and those who stated they regularly exercised, but this agreement was more pronounced among white students (73% vs. 62% for black students). White students were significantly more knowledgeable than black students on the exercise knowledge subscale. No significant differences existed between black and white students on any other HBM subscales. When subscale scores for those in good versus poor physical condition were compared, significant differences were found on all subscales except the perceived benefits subscale. Analysis of individual questionnaire items which best predicted whether one was in poor or good physical condition found four items accounted for 38% of variance in black students, and seven items accounted for 52% of variance in white students.
